Docket No.: OSTEONICS 3.0-466

IN THE CLAIMS

1. (currently amended) An orthopaedic trial augment
comprising:

a first block; and

an expansion member including a second block slidably
associated with the first block so that that the trial is
expandable in at least one direct ion_j_

wherein the first and second blocks are biased such
that the blocks expand in the at least one direction, and
wherein the trial augment is configured to be used with a
femoral trial .

2. (canceled)
3- (canceled)

4. (currently amended) The orthopaedic trial augment
of claim 1^3-, wherein a spring is associated with at least one of
the blocks and configured to bias the blocks in opposite
directions and expand e#— the trial .

5. (currently amended) The orthopaedic trial augment
of claim wherein one of the first or second blocks includes
at least one channel and the other of the first or second blocks
includes at least one complementary surface configured to
provide sliding movement between the first and second blocks.

6. (currently amended) The orthopaedic trial augment
of claim 1.3-, wherein one of the first or second blocks is keyed
to fit inside the other of the first or second blocks to permit
sliding movement between the two blocks in at least one
direction.

7- (original) The orthopaedic trial augment of claim
6, wherein one of the first or second blocks includes at least a
pair of grooves adapted to receive complementary surfaces on the
other of the first or second blocks.

32. (new) An orthopaedic trial augment for

engaging a cavity in a condylar portion of a trial distal
femoral component comprising:

a first block having an end portion for engaging an
anterior end of the cavity in the condylar portion;

a second block having an end portion for engaging a
posterior end of the cavity in the condylar portion, the second
block slidably mounted on the first block

a spring element engaging the first and second blocks
for moving the ends of the first and second blocks into biased
engagement with the anterior and posterior ends of the cavity;
and

at least one of the first and second blocks having a
proximally facing bone contacting surface.
